How a VC Can Affect Your HeartA lot of people experience occasional PVCs and have no issues. However, if they happen frequently, PVCs can weaken your heart muscle and increase your risk of heart failure.The heart’s rhythm is controlled by a group of fibers located in the upper right-hand corner of your heart. This is called the sinoatrial nerve, or SA. Electrical signals are transmitted to the ventricles, or lower chambers of the heart.CausesPVCs happen when the electrical impulse which normally triggers your heartbeat at the Sinus Node (also known as the Sinoatrial or SA node) does not. The impulse actually starts in the ventricles, causing an irregular heartbeat. These extra beats are also known as ventricular tachycardia, and ventricular fibrillation. It could feel as if the heart skipped a beating or feels like it is fluttering. They can occur rarely, causing no symptoms, but they could also happen frequently enough to impact your quality of life. Your doctor may prescribe medication if they are frequent or cause dizziness, weakness or fatigue.PVCs are generally harmless and do not increase your risk of heart disease. Over time, frequent PVCs can weaken the heart muscle. This is especially relevant if they are triggered by a heart disease such as dilated cardiomyopathy arrhythmogenic right ventricular cardiomyopathy, which may lead to symptomatic heart failure.PVCs can cause symptoms such as a feeling of your heart racing a beat, or fluttering. You may also feel exhausted. The fluttering may be more noticeable when you exercise, or consume certain foods or beverages. PVCs are more common in those suffering from chronic anxiety or stress. Some drugs, like digoxin, amiodarone, and cocaine, can also increase the risk of developing PVCs.If you are experiencing occasional PVCs Your doctor may suggest lifestyle changes and medication. If you are prone to frequent PVCs, your doctor might suggest that you stay away from certain foods and drinks such as alcohol and caffeine. You can also take steps to reduce your stress, and get plenty of sleep and exercise.If you have a lot of PVCs Your doctor might suggest a medical procedure called radiofrequency catheter ablation. This procedure destroys the cells that cause them. This is done by a specialist called an electrophysiologist. It is usually effective in treating PVCs and reducing symptoms, however, it doesn’t prevent them from occurring in the future. In some instances it may increase your risk of having atrial fibrillation (AFib), which can cause a stroke. This is rare but can be life-threatening.SymptomsPremature ventricular contractions, or PVCs, can cause your heart appear to flutter or skip one beat. These extra heartbeats are generally harmless, but you should consult your physician in case you experience frequent episodes or symptoms like dizziness or weakness.The normal electrical signals start in the sinoatrial, located in the upper right-hand part of the heart. They then travel to the lower chambers, also known as ventricles, where blood pumps are located. The ventricles contract to push the blood into the lung. They return to the center to begin the next cycle of pumping. But a PVC starts in a different location that is separate from the bundle of fibers, known as the Purkinje fibers, in the lower left part of the heart.When PVCs occur, the heart may appear to be racing or pounding. If double glazing doctor experience only a few episodes, but no other symptoms, the cardiologist probably won’t treat you. If you’ve got a lot of PVCs the doctor may recommend an electrocardiogram, or ECG to gauge the heart’s rate over a 24-hour period. The doctor may also recommend wearing a Holter Monitor, which records your heartbeat and tracks the number of PVCs.If you’ve suffered a heart attack in the past or suffer from cardiomyopathy -an illness that affects the way that the heart pumps blood -and must be aware of their PVCs and talk to a cardiologist about changes to their lifestyle. These include abstaining from caffeine, alcohol, and smoking, managing stress and anxiety, as well as getting enough rest. A cardiologist can prescribe beta blockers to slow down the heartbeat.Even if you don’t have any other indications however, you should have PVCs examined by an expert in cardiology if they occur often. These extra heartbeats may indicate a problem in the structure of your heart or lungs and if they happen often enough, can weaken the heart muscle. But the majority of people suffering from PVCs don’t experience any problems. They are interested in knowing if the rapid heartbeats, or the skipping of heartbeats is normal.DiagnosisPVCs can be akin to heartbeats that are fluttering, especially if they are frequent and intense. People who experience them regularly may feel faint. They can also happen with exercise, though many athletes who get them don’t have any problems with their health or heart. PVCs may show up in tests like an electrocardiogram, or Holter monitor. These use sticky patches with sensors to record electrical signals from your heart. A cardiologist may also use an ultrasound echocardiogram for examining the heart.A doctor may be able to determine if a person is suffering from PVCs from a history and physical exam. But sometimes they might only be able to detect them when they examine the patient for other reasons, for instance following an accident or surgery. Ambulatory ECG monitors are able to detect PVCs and other arrhythmias. They are able to detect heart disease when there is a concern.If your cardiologist concludes that your heart’s structure is normal, reassurance is the only treatment required. If your symptoms are troubling or cause you to feel anxious, avoiding alcohol, caffeine and other decongestants and reducing stress may aid. Regular exercise, being at a healthy weight, and drinking enough water can reduce your episodes of PVCs. If your symptoms continue or are severe, talk to your doctor about possible medications that can control the symptoms.TreatmentIf PVCs don’t cause symptoms or happen rarely they aren’t usually in need of treatment. If they are frequent, your doctor might want to check for heart issues or suggest lifestyle modifications. You could also have a procedure to get rid of them (called radiofrequency catheter ablation).If you have PVCs in your heart, the electrical signal which creates your heartbeat is located other than at the sinoatrial (SA) node that is located in the upper right corner of your heart. This could cause it to feel like your heart skips beats or has a few extra beats. It’s unclear what causes these, but they’re more frequent in those with other heart problems. PVCs are more likely to occur as you age, and may be more frequent during exercising.A doctor should perform an ECG as well as an echocardiogram on a patient that has frequent and painful PVCs to identify structural heart conditions. The doctor will also likely conduct an exercise stress test to determine if the increased heartbeats are caused by physical exercise. A heart catheterization, cardiac MRI or nuclear perfusion study can be done to look for other causes for the increased beats.Most people with PVCs don’t experience any issues and can live an ordinary life. They could increase the risk of developing dangerous heart rhythm disorders, especially if they occur in certain patterns. In certain cases, it means the heart muscle gets weaker and is unable to pump blood through your body.A regular, healthy diet and regular exercise can reduce your chances of developing PVCs. Avoid foods that are high in fat and sodium, and limit your consumption of caffeine and tobacco. Stress and sleep are also important. Some medicines may also increase your risk for PVCs. If you take any of these medications it is crucial to follow the advice of your doctor about eating healthy and exercising as well as taking your medication.Studies of patients who had an excessive amount of PVCs (that’s more than 20% of their total heart beats) discovered that they had a higher incidence of arrhythmia-induced cardiomyopathy. Certain people may require a heart transplant.
